The South East European Research and Education Networking (SEEREN) infrastructure interconnects the Research and Education Networks (NRENs) of Albania, Bosnia-Herzegovina, Bulgaria, FYR of Macedonia, Greece, Hungary, Romania and Serbia-Montenegro amongst themselves and to the European backbone network. In this respect, it constitutes the South-Eastern European segment of the multi-gigabit pan-European Research and Education network, GÉANT.

The SEEREN infrastructure was officially inaugurated in January 2004, with first IPv4 services provided in November 2003. Since then, the project has been developing several services and tools on top of the infrastructure, including a virtual network operations centre and a one-stop-shop for the management tools [SEEREN]. The deployment of IPv6 services has been planned since Spring 2004.
